Tollus is betraying Kas because he want's to take her power for himself, idk the assassin's motivation but she works for him, Kas want's the ring to keep you soul safe for whatever weird plan she has for it with her obsession over you, I think the traitor is the senetor guy, well, the traitor that's not Kas in disguise anyway, the calise think is just her fucking around in cosplay as herself when she was human.So...Kasyrra wants the ring. She sends her demon minions to go get it for her, and the deadly assassin that works for Tollus is going along for the ride or going on her own all so she can maybe fix herself with it. She then asks you to help her get it as well while in disguise. You have the option to keep it or give it to the demons to take to kasyrra. Doesn't matter because the quest ends the same way. Then the assassin just stabs Calise...who is apparently Kasyrra?
So is it implied during the royal feast that Calise is the traitor? Too many characters, too many words, and so few of it feels well written. I know it's a well beaten dead horse at this point, but it's still wild to me that the original coc did so much more with fewer characters and shorter scenes.
There, that's pages of plotline condensed into a paragraph.
